Question

A certain number of people are sitting in a row, facing north. P is to the immediate left of Z. Only one person sits between G and D. G is to the left of D. H is fifth to the left of G. K is to the immediate right of D. P is third to the right of K. If no other person is sitting in the row, what is the total number of persons seated?

• A. 10
• B. 11
• C. 12
• D. 13

Answer 1

Answer:

D. 13

The total number of persons seated is 13.

Step-by-step layout from left to right:

1. Place G, D, and K based on the rules ("G is to the left of D with one person between them" and "K is to the immediate right of D"):
   G [ ] D K

2. Add H ("fifth to the left of G"):
   H [ ] [ ] [ ] [ ] G [ ] D K

3. Add P and Z ("P is third to the right of K" and "P is to the immediate left of Z"):
   H [ ] [ ] [ ] [ ] G [ ] D K [ ] [ ] P Z

Counting all the slots from H to Z yields exactly 13 positions.
